Nigrastriatal terminals:  iontophoretically injected PHA-L (brown, Vector DAB). Zoom

Overview

    Phaseolus vulgaris agglutinin is the name ascribed to a family of lectins, each of which consists of four subunits. There are two different types of subunits. One appears to be involved primarily in red cell agglutination and has been designated the “E” subunit (for erythroagglutinin). The other type is involved in lymphocyte agglutination and mitogenic activity and has been termed the “L” subunit (for leucoagglutinin). These subunits combine to produce five isolectins.  PHA-L, with four "L" type subunits, does not agglutinate red cell but is a potent mitogen.

    Phaseolus vulgaris agglutinin is the name ascribed to a family of lectins, each of which consists of four subunits. There are two different types of subunits. One appears to be involved primarily in red cell agglutination and has been designated the E subunit (for erythroagglutinin). The other type is involved in lymphocyte agglutination and mitogenic activity and has been termed the L subunit (for leucoagglutinin). These subunits combine to produce five isolectins.

    One of these isolectins has four E subunits and is designated PHA-E. PHA-E possesses strong hemagglutinating activity but is a poor mitogen. PHA-L, with four L type subunits, does not agglutinate red cells but is a potent mitogen. The other three isolectins, designated E3L1, E2L2, and E1L3, have erythroagglutinating and mitogenic activities proportional to the number of respective E or L subunits. We have termed the mixture of the five isolectins PHA (E+L).

    PHA-L has been found to be an excellent, specific marker for use in anterograde neuronal tracing.

    After iontophoretic injection of PHA-L, the approximate rate of anterograde transport is about 4-6 mm/day, with survival periods of over 18 days having been observed. Once transported, the PHA-L is best visualized for light microscopy with antibody to the lectin, followed by the appropriate detection system and substrate. Fluorescent staining can also be used for a faster staining procedure. A complete applications protocol is available upon request.
